PITTSBURGH — A lawsuit filed to federal court today hopes to hold the Butler School District and its former superintendent accountable for allowing students at Summit Township Elementary School to be exposed to lead.

The lawsuit, which is intended as a class-action suit, was filed by attorneys with Dallas W. Hartman P.C. and Myers, Lupetin and Unatin on behalf of district resident Jennifer Tait whose daughter attends Summit school, and “all other similarly situated individuals.”

“One claim is negligence and another is medical monitoring. We are seeking to compel the school to provide more extensive medical treatment and testing,” attorney Brendan Lupetin said.

A federal judge will eventually rule whether the suit will be a class-action claim. The class would potentially include all the students who attended the school this year as well as district staff members and any one else who would have visited the building, Lupetin said.
